Why is a distinction made between atmospheric ozone and ground-level ozone?
Answer and explanation
Correct answer: Upper ozone is protective while ground-level ozone can be a pollutant
Ozone has different effects according to its location. Stratospheric ozone forms the ozone layer and absorbs much of the Sun’s harmful ultraviolet radiation, helping protect living organisms. In contrast, ozone near the ground is a secondary air pollutant formed through reactions involving nitrogen oxides and sunlight; it can irritate the lungs and damage plants. Hence option B is correct, while the other statements reverse or deny these effects.
